Tenure was originally created to protect college professors from being dismissed for poor reasons, such as favoritism, race, political party, or becoming pregnant. In 1900, the first meeting of the National Education Association brought the idea of academic tenure to the attention of the nation, and led it into state legislation for the first time in New Jersey ten years later, granting basic "fair-dismissal rights" to post-secondary education professors (time). Suffrage activists took tenure into elementary and high school instructors in the 1920's when they argued for the position of women teachers disapproving of sexist employers (time). The difference between college tenure and the tenure granted to teachers of primary or secondary education, however, is that college professors are required to present evidence of their competence, while the lower grades' teachers can be granted it just after working for a few consecutive years (time). A few states have attempted to remove or replace tenure, but to little avail as the teachers' unions have rooted in with it to protect their members from being unemployed.
